Questions and Answers

What does it mean when an object is said to be at rest?

The object has zero velocity relative to some reference point. (correct)

The object is in a state of constant acceleration.

The object is moving at a velocity of 65 MPH.

The object is not affected by any external forces.

Which statement about acceleration is true?

Acceleration has no effect on an object's state of motion.

Acceleration involves a change in velocity. (correct)

Negative acceleration results in the velocity remaining constant.

Positive acceleration occurs when an object decreases its velocity.

What is the primary factor responsible for causing motion in objects?

Velocity

Friction

Acceleration
